SPECIFICATION forming part of' Letters Patent N o. 456,128, dated July14, 1891. Application ledDeceniherll',1888. Serial No. 293,324. (Nomodel.)

To all whom it 'muy con/cern,.- A

lle it known that I, Josemi Damme, of Karns City, in the county ofllutlcr and State of lennsylvania,'have invented'a new and usefulImprovement in Iumps, of which the following is a specification.

My invention is an improvement in pumps intended especially for use indeep wells, whether oil or water wells, and seeks, among otherimprovements, to provide, in connection with a trap-valve at the bottomof said wells, 'novel constructions by which said trap-valve may bepositively opened when the standing valve of the pump is inserted;further, to provide novel constructions which will effect the opening ofthe trap-valve on the insertion i ol' the standing valve and willpositively close such trap-valve when the standing valve is removed,and, further, to provide other improvements, as will behereiimfterdescribed.

l'lheinvention consists in certain features of construction and novelcombinations dt parts, as will be described and claimed.

In the drawings, Figure 1 is a longitudinal section of a portion of alwell provided with my improvements. Figs. 2, 3, and 4 are detail viewsof the trap-valve and mechanism for operating the trap-valve. Fig. 5 isa detail View illustrating the means for preventing baekfiow in ease ofbreakage of rods; and Figs. 6 and 7 show modified forms of trapvalve anddevice for operatingr the same, as will be more fully describedhereinafter. Fig.

S is a detail view of the nut on the lower endof the plunger, all ofwhich will be hereinal'ter more fully described; and Fig. ll shows themanner of connectingI the tripper -with the standing valve.

In deep wells, particularly oil-wells, when the pumping devices areremoved for any purpose the ilow of water and air, the., from the tubeback to the oil or water source operates detrimentally. To avoid this,trap- -valvcs have in some instances been designed for use at the bottomof the tubing controlvrling the inlet-opening,` fertile-water, so thatvsuch trap-valyes will he closed when the pumping devices are withdrawn;but so far as I am informed such trap-valves are opened and closed witheach reciprocation of the pumping-plunger, 'so that the said trap-valveand its seat soon become worn and need replacing or repairs, .whichnecessitate the removal of the well-tubing. Such operation is difficultand expensive in several ways, since it involves a stoppagc'of work fora considerable time vand an injurytothe well from the withdrawal of thetubing. This injury to t-he'well from the withdrawal of the tubing isespecially experienced in those wells inv which gas or vacuum pumps areemployed, as on withdrawing the tubing in such cases the air rushes inand it is sometimes weeks before the former production can be obtained.

An important feature of my inventionis the provision of devices wherebythe trapvalve will be opened on the insertion of the support or blockfor the standing valve and will be held open so long as suchvalve-snpportremains in operative position and will be closed on theremoval of the said standing valve, so that the trap -valve is onlymoved at t'hc time the standing yalve is insorted and `when such part isremoved. As such insertion and removalA of the standingvalve only occursin some instances at intervals of about thirty days, thereis practicallyno wear on the trap-valve, and snchl'iart, when once inserted, will inthe ordi-nary course ofthings wear for many years without needing anyrepairs whatever.

Before proceeding to the detailed description ofthe'particular;constructionswhich I employ for secu ring the ends beforedescribed, I desire testate with reference to the accompanyingillustration that in Fig. l Ishow the pump-mechanism tubing, barrel, orcasing valves, tl:c eonstructed I tice tomake them. 4

Figs. Gand 7 show modified constructions of the valve-operating devicesand lthe trapvalve, such constructions shown in Figs. G and 7 being to acertain extent equivalents of the preferred constructions shown in'liig.1.

rlhe well-'tubing A is provided atits lower end with a section di,reduced in diameter, so that the pump devices which fit and operate insuch section may be nio/ved conveniently down to and liftedfromsuchseetion, it being only necessary to use addit'ona'l force to seatroti the said parts" in Yand ,jar 4or dislodge them from suchsection, they moy-ing freely down 4to and up" from such' section when sodesired.

At its lower end'the section cris coupled prefer in praeto or otherwisesuitably provided with the trap valve i3, which comprises the valveproper C and the casinggD therefor', the latter being providedwitlrflatcral parte (l, and the valve C being journalcd in the casingand having parte c, which regieter in the proper adjnstmentot the valvewith theparte 'v d and permit the entry of iluid', or are set out oi'regieter with such parte to stop olf the iiow of fluid through same whenthe valve is closed. upward tubular extension E, which is sloltedlongitudinallynt diametrically-opposite pointe at F, such slots beingformed -with straight lower portions jf and spiral orinclined' 'upperportions j", the latter forming practically spiral contacteur-facce, thecontact with which of the operating' part, which is movedlongitudinally, but is held from ro tary movement when in contact withsuch surfaces f', will cause a rotation or partial rotation ot' thevalve to positively open or close the saine, an may be desired. Thelower straight portions f ot' the slots arepreferred, because theypermit a limited play of the operating part withoutatlecting anyvariation of position of the valve.

To hold the valve-operating device pres ently described from turningwhen in contact with the spiral surfaces, I provide the fixed hearingsG, which extend adjacent the spiral contact-surface end are engaged bythe tripper the latter is moved longitudiy nallyin contact with thesurfaces f and hold the valve-operating device from turning when in suchcontact. The upper ends of bearinge G are pointed, being beveled fromthe center downward on opposite sides to properly direct the tripperinto operative contact with the spiral surfaces f.

ln the. construction shown in Fig. l. the valve-operating device lir ispractically a portion or part oil'the standing valve, being` swiveled atits upper end to the lower end ot the main portion or body of thestanding valve, which thus forms the Support for the part li, and thelat-ter is formed with depending` arms il and a cross-bar h, connectingsuch arme near their lower ends, which bar h may or may not be providedwith an antifrictien roller or rollers, as shown. 'lhe arms ll havetheir lower ende` pointed like the upper ends of the fixed hearings (l,and are adapted when lowered to slide down between the Seid parte, aswill be understood from the drawings, the bar 7L passing down in theslot l?, engaging the spiral contacteurface and turning the valve toopen such valve as the partitie lowered or close it as the said partraised. It will be neen that the" arms-Il',Y meeting hearings G, areguided thereby, so as to properly present the bar h to engage thecontact-surfaces f. 4 l

i In ewiveling the part li, I prefer to forni its upper end with anipple l, having an external annular groove i.. l

Un `the lower end of the standing valve J',

TheA valve C is A forn'ied with an,-

fieaiee I form a tubular extension J, above which is a threaded portionor hearing-j. 'The coup ling-piece li has ils upper end threaded to lithearingj, and its lower porti-on is cut away at 7:. on one side toreceive the nipple l'1 which may' he moved through opening k laterallyinto the lowerpportionol the coupling, the

' Sion J lits in the ni pplel and holds such part trom lateral movementout through the opening ligand the flange kfitting in groove i, holdsthe parte I( l from longitudinal detachment. The part ll ie consequently ewiveled in position in a simple convenient manner.

rlhe ahove construction of valve-operatlng devices, dac., refers, aswill he underetiinxl, to the construction Shown in Figs. l, 2,3, and 'l.'lhe constructions shown -in Figs. (j and 7 represent modifications, orwhat may he regarded as, to a certain extent, equivalents ot thepreferred construction before described. In Figs. G and 7 'the form oftrapva'lve ie different 4lroni that shown in Fig. l, it beingpractically a damper-like disk having openings l), which may be turnedinto and out of register with openings 10 in the bottoni plates of thecasing ll. lhis forni of valve haa een;

trail f an 'annular Socket lELand thc ease is provided 'above suchsocket with a spiral hearing 13. The valve-operating device in suchcaseis a rod 14, swiveled 'to and depend ing from the standing valve,such rod being' formed with an angular' portion l5 to enter the opening12 and a spiral portion 1U to engage the spiral bearing 13, the parteheingno arranged that alter the part l? has entered socket l2 theportion 1G will engage Spiral hearing 1S and cause-the rod 'hl torevolve, nd :so turn the valve to open the latter' an "the said rod isinserted and close such valve as it is removed.

lhe construction shown in Fig. 7 is sui)- etantially the saine thatshown in llig'. 6, the difference being that in Fig. 7 the angu-V larhearing is provided in the case and the Spiral bearingin the valve, thedepending rod being properly formed "o correspond vwith changeofconstruction. f nthslastconetruction there iS pr ovided a fixedbearing', and the valve has a spiral contact-surface, the depending rodhaving a portion lo engage the valve J, it will be seen, is suitablypacked, and is provided with an upwardly-opening valve j', and when thebarrel L is used this standing valve or valve-block J" is usually`turned inte/the lower end of the barrel, such barrel fitting snugly insocket a of the tubthe lower end of the barrel to form or carrythe'tripper. This barrel is made quite thin, and the space between itandthe tu bingwhen such space is unfilledrenders the bursting of the barrelby the pressure within the barrel a possible and likely. .'lo avoid thisI forni a vent'or opening L in the barrel, preferably immediately belowthe upper packing l, so

vVent any' damage to the barrel.

Athat the oil or waterwill pass out and till the space-between thebarrel and tube or,

socket, andso equalize the pressure and pre- A check- 'Valv'e L2 isusually supported at or immediately above the upper end of the barrel,the support of such cheek-Valve being packed at Z2 a'nd provided withguides for the pumprod Mf/'lhc rod M extends into the barrel andconnects with the plunger N, which has an upwardly-opening valve n. Thisplunger N, as shown in Fig. i, operates in the removable barrel L,beingsuitably packed therein, and has at its lower end the inletopening 9L',which tits a valve portion N on the upper end of the stand-valve whenthe plunger and stand-valve are in contact, so that in case of anybreakage of the rods the plunger will fall into contact with thestanding valve and the part N will close openingn and prevent anyflowot' water down through the plunger. It would seem that the valvesj', 1r, and L2 would prevent any backilow oifwater or oil; but when itis considered that leaks are in tentionally produced by filing orotherwise in the seats of valves used in the class of pumps to whichmyinvention relates the importance vided. with my limproved trap-valve;but I' prefer to use such trap-valve, as before stated.

It is preferred to use. the barrel and to lit "thestanding valve andplunger' therein -for convenience in removingtlnl standing valve,

and also t'o provide a eonstriujction whiehwill receive the wear of theplunger and ma)` be jeonveuiently removed when worn out for thesubstitution of a new barrel. It will be understood, however, that whendesired the barrel may be omitted and the standing valve be supportedand the plunger be operated direetly in the well-tubing withoutdeparting from some of t-hebroad features ot my invention. When so used.I adapt the plu-nger to be adjusted inioconneetion with Ilmsiandingthisend, as shown in Fig. S, I provide a threaded stein or tenen 0 on thelower end of the plunger, forming the lower end of such tenon O withalongitudinal slot 0. The upper end of the standing-valve block orsupport has a socket P, threaded to receive tap 0.

'lo prevent the tenen froinbeing forced by its longitudinal movementinto socket P and destroy the threads as the plunger is operated, Iprovide a nut Q, having a detent or latch g, operating in a slot leadingradially outward from its threaded bpre. This detent orlateh is'pivotedat its outerend in the said slot, and has its inner end-toothed orformed to correspond with the threadsof the nut. Theretore when turnedup in its slot the latch will coincide with the threads of the nut, andthe l latter maybe turned on the tenonO; but when turned on the end ofsuch tenon and thelatch is brought to register with slot o the latchwill fall so its uppertooth will rest in slot o and lock the nut fromturning. Vhen; however,itis desired to lift the stat'ii'ing Valve, theplunger is vlowered to such partand the contact forces the detent intothe slot, when the plunger may be turned to turn the tenon 0 through thenut into the standing-valve block, when the latter maybe withdrawn byelevating the plunger.

In: the construction shown inFig. l there is provided a shoulder at a:on the rod engaging a shoulder y in theY bai-Vitel, Aso that the eleva'-tion of such rod beyondits normal operatingpoint .sf'illclevate thebarrel and its contents.

'iheoperation ol' such construction shown in Fig. l-will,it is believed,be fullyunderstood from the foregoing description.
